Document Type and Number:
WIPO Patent Application WO/2021/109120
Kind Code:
A1
Abstract:
A crop growth condition evaluation method and device. The method comprises: obtaining a color image of a target area; determining color information corresponding to the target area in at least two color channels according to the color image; and according to the color information corresponding to the target area in the at least two color channels, determining a parameter for indicating a growth condition of a crop in the target area. In the present application, the parameter for indicating the growth condition of the crop in the target area is determined on the basis of the color image of the target area. Evaluation of the growth condition of the crop in the target area can be realized by using a normal camera instead of a professional multi-spectral camera, thereby greatly reducing operation costs and providing a quantitative decision basis for the operation.
